Answer:
Ohn has paid $5730 in first 20 installments
Step-by-step explanation:
As per the question Ohn payed the first installment =$100
Next month Ohn payed the installment = 1.1×$100
Similarly subsequent installment =1.1×1.1×$100
So we can write first 20 installments as
⇒100+100×1.1+100×1.1²+100×1.1³.........+100×
And we know in geometric series
1+x²+x³+...........
= (1-
)÷(1-x)
Therefore sum of first 20 installments will be
⇒100(1+1.1²+1.1³............ =(1- )÷(1-1.1)
= 100(1-6.73)÷(-.1)
=100×5.73÷.1
= $5730
So Ohn has paid $5730
The first and the second one.
-2*-2=4
Absolute value of -4 is 4
Answer:
C. 115°,65°
Step-by-step explanation:
Make the equation for ∠A equal the equation for ∠C: 100+5x=106+3x. You will find x=3. So you plug that into the equations for ∠A and ∠C. And you know that ∠A and ∠C both equal 115°. You repeat these steps for angles B and D and they equal 65°. Ya welcome.
Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86
